One Home Made NES To Rule Them All
The Nintendo Entertainment System, or Famicom depending on where in the world you live, is a console that occupies a special place in the hearts of people of a certain age. If you lived in a country that Nintendo didn’t ship its consoles to in the late ’80s and early ’90s though, you might think that it would be an experience that would have passed you by. Eastern Europeans for instance didn’t officially meet Mario for years.
Fortunately for them there was an industry of Chinese and Taiwanese clone makers whose products were readily available in those markets. For the …read more
An Open Source 96 MSPS Logic Analyzer For $22
If you are in the market for an inexpensive USB logic analyser you have a several choices, but few of them deliver much in the way of performance. There are kits from China for a few dollars using microcontrollers at their heart, but they fail to deliver significant sample rates. If you require more, you will have to pay for it.
It is therefore rather interesting to see [kevinhub88]’s SUMP2 project, an open source logic analyser with a claimed 96 MSPS sample rate using an off-the-shelf Lattice iCEstick FPGA evaluation board that only costs about $20.
It talks to a …read more
Converting a TP Link Router to Mission Control for Cheap 433MHz Home Automation
[Jean-Christophe Rona] found himself with some free time and decided to finish a project he started two years ago, reverse engineering cheap 433MHz home automation equipment. He hopes to control his space heaters remotely, in preparation for a cold and, now, robotic winter.
In a previous life, he had reverse engineered the protocol these cheap wireless plugs, garage doors, and electric window shutters all use. This eventually resulted in a little library called rf-ctrl that can toggle and read GPIO pins in the correct way to control these objects. He has a few of the more popular protocols built into …read more
Why You Should Own A Sewing Machine
In our hackspace, we’ve opened a textile room in the last month. We have high hopes for it as a focal point for cosplayers and LARPers as well as the makers of wearable electronics and more traditional textile users. Putting it in has involved several months of hard work bringing a semi-derelict and previously flooded room that was once the walk-in safe for our local school authority to a point at which it is a light and welcoming space, but a surprising amount of work has also had to go into winning the hearts and minds of our community for …read more
Botnet Recall of Things
After a tough summer of botnet attacks by Internet-of-Things things came to a head last week and took down many popular websites for folks in the eastern US, more attention has finally been paid to what to do about this mess. We’ve wracked our brains, and the best we can come up with is that it’s the manufacturers’ responsibility to secure their devices.
Chinese DVR manufacturer Xiongmai, predictably, thinks that the end-user is to blame, but is also consenting to a recall of up to
300 million 4.3 million of their pre-2015 vintage cameras — the ones with hard-coded factory …read more
